Experiments on the deployment of umts


The project seeks to identify a smooth transition path from disparate and second generation mobile systems towards UMTS, focusing on evolution of Core Network capabilities supporting both terminal and personal mobility for a number of services provisioned to selected sectors (e.g. helath care, businness travellers). The objectives of the EXODUS are:
demonstrate terminal and personal mobility, spanning both public and private operating environment, using systems which support multimedia services
identify, implement and demonstrate IN functionalities to meet UMTS requirements
identify, implement and demonstrate enhancements on ATM-based switches to support mobility management.
Up to date achievements:
Phase I: technical detailed specifications, implementation of all the network elements and detailed planning of the user trials;
Phase II: high level architecture definition, detailed technical specification of all the network elements and framework for trials and demonstration.

Key results produced by EXODUS will be:
real migration path towards UMTS from existing mobile and fixed systems
Core Network enhancements to meet UMTS requirements
experience with a system implementing Broadband Services in a terminal and personal mobility environment
evaluation of user acceptance of the implemented set of services.
Expected Impact
Within RACE II considerable effort has been devoted to definitions of advanced approaches to personal communications, but not oriented to implementations and field trials. EXODUS aims to implement and deploy UMTS platforms, capitalising as far as possible, on the work and equipment developed in the above cited research projects. On this platforms EXODUS will perform experiments and field trials with real users to demonstrate and test some of the concepts resulting from theoretical studies carried out in the frame of RACE II.
Synergy within the consortium inside and outside the project framework is expected to positively impact on the performance of European businesses.

Main contributions to the programme objectives:
Main deliverables
Validation of enhancements on an ATM-based B-ISDN to support mobility and IN functionalities to meet UMTS requirements
Contribution to the programme
EXODUS establishes a transition path from current disparate fixed and mobile systems to the integrated UMTS, focusing in the core network capabilities to support mobility (both terminal and personal mobility)
Technical Approach
The transition path to UMTS is demonstrated using an evolving experimental platform with real users, covering strategically important application sectors. The project has started from a narrowband platform, based on an Intelligent Network Capability Set 1 supporting personal and terminal mobility for voice and specifically enhanced for data services, in the public, private and residential domains. DECT is used as radio access.
The evolution of this overall platform towards UMTS is addressed, in Phase II experiments, to determine the relevant impact on the Core Network, INAP and UNI signalling protocol. The phase II platform will comprise a Broadband Core Network, with an advanced IN infrastructure, supporting both personal and terminal mobility for multimedia services; the Service Control Point will evolve to support the new services, while the ATM switch will include enhanced functions for mobility support. The signalling protocols at the UNI are extended too, to take into account both evolutionary services requirements and mobility aspects
Summary of Trials`
On the initial platform a two sites field trial involving about one hundred of real users is performed to verify the usability and the perceived quality of service on Spring '97. Data and voice services for Cordless Terminal Mobility access are provided.
The final platform will be based on three experimental islands, all sponsored by National Hosts.
Two user trials are foreseen:
the mobile multimedia trial which comprises:
multimedia data retrieval
direct playing
collaborative work;
The trial will be deployed in a business environment, and the target users will be employees of Italtel and CSELT, and friendly customers of Swiss PTT;
the health care trial which encompasses:
multemedia services
on three Hospital Bed Units and one fixed Nurse/Doctor Terminals for telemonitoring in the University Hospital of Basel.
Moreover a joint trial with AC095 ASPeCT will be carried out to demonstrate Trusted Third Party services and advanced UMTS authentication mechanism.
Key Issues
Key issues of EXODUS are:
focus on the Core Network
strong orientation towards experiments and user trials
close link with the ACTS National Host initiatives
strong participation in the standardisation process.
